So...Os, I just realized that I unintentionally made a combo when I rebuilt Ice Beast.

How would you like Frozen Faculty Furtherance: Spirit to interact with Leeching Cold? As written Spirit now applies to everything (which normally wouldn't happen until level 10) since everything requies a save from Leeching Cold.

Quote from: Frozen Faculty Furtherance: Spirit

The Ice Beast is no longer subject to nonlethal damage, precision damage, or extra damage from critical hits as well as gaining immunity to all mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects). In addition, any time the target of an Ice Power fails its saving throw, it succumbs to mild hypothermia and becomes fatigued for as long as it is under the effects of that Ice Power (minimum 1 round). This is in addition to any other effects of the Ice Power.

Quote from: Leeching Cold

Any time the Ice Beast deals cold damage with an Ice Power (including Ice Magic), the target must make a Fortitude save (DC 10 + 1/2 HD + Wis mod) or be entangled for one round per 2 Ice Beast levels (minimum 1). The target only needs to make this saving throw the first time they take cold damage from the Ice Beast each round from an Ice Power.

Companion- Some rats can become quite friendly. If it enters the space of an allied creature of bigger size it can climb on them and Hide as a free action, counting the ally as cover. If the allied creature moves while this ability is active the Rat goes along. If the allied creature performs a melee attack while this ability is active the Rat can move into the opponent's space as a free action without provoking attacks of opportunity. If the Rat was hiding the enemy gets a new Spot check but if they fail they're unaware of the Rat's presence.

I didn't update my post with the rolls I made (which finally started working a little while ago), but I'm still good to go if everyone else is. I'm keen to keep seeing how the Spellshaping works out, since there are so few opportunities to use homebrew which don't fizzle out.
